CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 300,342, dated June 17, 1884.

Application filed Api-i124, 1884, (Xo model.)

.To (LH 'fu/71,0111, it 71mg/ concern:

Be it known that I, FRED EV. BUnNs, a citizen of the United States, residing at Leinars, in the county of Plymouth and State of Iowa, have invented certain new and useful Imin'ovenients in Carpet-Stretchers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being` had to the annexed drawings, making a part of this specification, and to the letters and iigures ofrefcrenee marked thereon. l

Figure l of the drawings is a perspective view of a carpet-stretcher constructed in accordance with my invention; and Fig. 2, a detail view partlyin section and on an enlarged scale, showing the eccentric clamp in a raised position in dotted lines.

The present invention has relation to that class ol" carpet-stretchers in which are employed two hinged bars, the outer one having a suitable claw to engage with the carpet, and the inner bar having an extensible arm, so that the device can be lengthened or shortened, as circumstances .require The means heretofore employed for holding the arm in an eX- tended position consisted, usually, of aratchetplate and pawl or like means, enabling the arm to be adjusted at each point of the tooth of the ratchet only, thereby any limited or fractional degree of adjustment at a distance less than the distance between the ratchetteeth was impossible.

It is the object of the invention to provide means whereby the extensible arm can be nicely adjusted at any point to lengthen or shorten the arm with relation to the bar upon which it is supported, thus better adapting the device to all classes of work, and in places where the ordinary carpetstretchers heretofore referred to could not be used. These objects I attain by the construction substantially as shown in the drawings and hereinafter described and claimed.

In the accompanying drawings, A represents a short bar to which the claw B is connected, said claw and bar being ol' any suitable construction and form and of any desira` ble material. The bar A is hinged to a similar but longer bar, C, to which is connected the extensible arm I), having secured to its end a guide, a, through which the bar G passes. The bar C has connected to it a yoke, b,which also serves as a guide anda bearing for a cam or eccentric locking device. E, provided with asuitable hand-lever, c, for operatingit. This device enables the arm to be extended with great nieety, and so iirmly held in position that any sidewise movement of the arm upon the bar is rendered impossible, while its siniplieity enables it to be manufactured at a trilling cost.

Having now fully described my invention, what I claim as new, and desire to secure by Le ters Patent, is-` A carpet-stretcher consisting of two arms hinged together, one of which i s provided with a suitable claw, an extensible arm, and a cani or eccentric locking device for holding the arm in an adjusted position, substantially as and for the purpose specilied.

In testimony that I claim the above I have hereunto subscribed my naine in the presence of two witnesses.

FRED XV. BURNS.
